Chapter 4, Problem 65GP

The fastest pitched baseball was clocked at 46 m/s. If the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1.0 m, and a baseball has a mass of 145 g,

a. Draw a free-body diagram of the ball during the pitch.

b. What force did the pitcher exert on the ball during this record-setting pitch?

c. Estimate the force in part b as a fraction of the pitcher’s weight.

While playing basketball in PE class, Michael Angelo lost his balance after making a lay-up and colliding with the padded wall behind the basket. His 56-kg body decelerated from 9.5 m/s to 0 m/s in 0.34 seconds. Determine the force acting upon Michael Angelo's body. a. F = 2354.2 N b. F = 1564.7 N c. F = 1897.3 N d. F = 3564.2 N

The froghopper, champion leaper of the insect world, can jump straight up at 4.0 m/s. The jump itself lasts a mere 1.0 ms before the insect is clear of the ground.a. Draw a free-body diagram of this mighty leaper while the jump is taking place.b. While the jump is taking place, is the force that the ground exerts on the froghopper greater than, less than, or equal to the insect’s weight? Explain.
